File exists action: Option to rename existing file, if duplicate uploaded

[Sascha]

Hi there at Filezilla,

it would be nice to have an option to rename the existing file rather then the one being uploaded in the "File exists action" preferences.

Use case:
I upload a modified .php file, but would like to keep the old version of that file for reference/backup.

At the moment to do this I have to rename the existing file by hand, which is rather tedious. Maybe the overwritten file could be named existing file name + the time and date when it was overwritten. Otherwise I guess just .backup or whatever will do.
Thanks,
Sascha

I am looking for this exact feature. It would be nice to upload new files to a server without worrying about losing existing files altogether. I agree on a rename of the file to include date/time, or at least just add ".bak" or something similar to the filename. The date/time option would allow for multiple backups of the same file.

Thanks for the great program guys!

I second this feature. If the server file can be renamed using a regex to add a suffix or rename the extension it would be great feature. Example, upload index.php to server with existing index.php, this gets renamed to index.php.Mar302017 or index_Mar302017.php or index.bck.Mar302017 or even a random hash index.bck.UIYFID%$DF etc. Many variants to be support, using a regex for flexibility would be great. Keep up the great work on FileZilla!
